Хроническая печеночная недостаточность (ХПН) и цирроз печени (ЦП) являются одной из классических причин различных минеральных нарушений: так, распространенность остеопороза среди пациентов с ЦП достигает 12–55%; у 40% пациентов с хроническими заболеваниями печени (ХЗП) происходят переломы различных локализаций. На сегодняшний день данные о нарушениях минерального обмена и костной патологии (таких как печеночная остеодистрофия, остеопороз, дефицит витамина D, вторичный гиперпаратиреоз, гипокальциемия) у пациентов с хроническими заболеваниями печени остаются ограниченными, что затрудняет своевременную диагностику и подбор оптимальной патогенетически-обусловленной терапии.</p></sec><sec><title>Цель</title><p>Цель. Изучить особенности минерального обмена у пациентов с ЦП различной этиологии, в частности обмена витамина D, выявить диагностически значимые маркеры нарушений минерального и костного метаболизма в данной популяции.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Все участники исследования (пациенты с ЦП и здоровые добровольцы) прошли анкетирование, антропометрию, лабораторное обследование для оценки состояния минерального и костного обмена (включая гормональные и биохимические параметры, метаболиты витамина D, чья концентрация измерялась методом тандемной масс-спектрометрии). Для оценки минеральной плотности костной ткани (МПКТ) проводилась рентгеновская остеоденситометрия поясничного отдела позвоночника, проксимального отдела бедренной кости и дистального отдела лучевой кости, рассчитывались значения трабекулярного костного индекса (TBS), также проводился скрининг компрессионных переломов тел позвонков методом рентгенографии грудного и поясничного отделов позвоночника в боковой проекции.</p></sec><sec><title>Результаты</title><p>Результаты. В исследование были включены 45 пациентов с ЦП и 20 добровольцев, составивших группу сравнения (СР), сопоставимые по полу и возрасту. В группе ЦП выявлены статистически значимые отклонения ключевых показателей минерального обмена относительно СР: снижение уровня общего кальция крови (2,27 vs. 2,38 ммоль/л, p&lt;0,001), ионизированного кальция (1,07 vs. 1,10 ммоль/л, p=0,007), паратиреоидного гормона (26,0 vs. 36,4 пг/мл, p=0,009) и инсулиноподобного фактора роста-1 (91 vs. 152 нг/мл, p&lt; 0,001). Отмечен выраженный дефицит 25(ОН)D (12,4 vs. 25,9 нг/мл, p&lt; 0,001) и снижение уровня 24,25(ОН)₂D₃ (0,6 vs. 1,5 нг/мл, p=0,001). При оценке состояния костной ткани обнаружен значимо более низкий трабекулярный костный индекс (TBS) в группе ЦП (1,370 vs. 1,498, p=0,001) при отсутствии различий абсолютных показателей минеральной плотности кости (МПК).</p></sec><sec><title>Заключение</title><p>Заключение. Результаты исследования подтверждают наличие особенностей минерального обмена у пациентов с ЦП: изменения метаболизма витамина D, гипокальциемию, снижение концентрации ПТГ, ухудшение микроархитектоники костной ткани (снижение TBS) при сохраненной МПК, что подчеркивает необходимость комплексного обследования пациентов с ЦП, а также дальнейших исследований настоящей проблемы.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: Chronic hepatic insufficiency and liver cirrhosis (LC) are among the classic causes of various mineral disorders. For instance, the prevalence of osteoporosis in patients with LC reaches 12–55%, and up to 40% of patients with chronic liver disease (CLD) experience fractures of various locations. To date, data on mineral metabolism disorders and bone pathology (such as hepatic osteodystrophy, osteoporosis, vitamin D deficiency, secondary hyperparathyroidism, and hypocalcemia) in  patients with chronic liver diseases remain limited, which complicates timely diagnosis and the selection of optimal pathogenetically targeted therapy.</p></sec><sec><title>AIM</title><p>AIM: To investigate the characteristics of mineral metabolism, particularly vitamin D metabolism, in patients with liver cirrhosis of various etiologies, and to identify diagnostically significant markers of mineral and bone metabolism disorders in this population.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: All study participants (patients with LC and healthy volunteers) underwent questionnaires, anthropometric measurements, and laboratory testing to assess mineral and bone metabolism status (including hormonal and biochemical parameters, and vitamin D metabolites, the concentrations of which were measured by tandem mass spectrometry). Bone mineral density (BMD) was assessed using X-ray osteodensitometry of the lumbar spine, proximal femur, and distal radius. Trabecular Bone Score (TBS) values were calculated, and screening for vertebral compression fractures was performed using X-ray imaging of the thoracic and lumbar spine in a lateral projection.</p></sec><sec><title>RESULTS</title><p>RESULTS: The study included 45 patients with LC and 20 volunteers who formed a comparison group (CG), matched by sex and age. In the LC group, statistically significant deviations in key mineral metabolism parameters were observed compared to the CG: decreased levels of total blood calcium (2.27 vs. 2.38 mmol/L, p &lt; 0.001), ionized calcium (1.07 vs. 1.10 mmol/L, p=0.007), parathyroid hormone (26.0 vs. 36.4 pg/mL, p=0.009), and insulin-like growth factor-1 (91 vs. 152 ng/mL, p &lt; 0.001). A pronounced deficiency of 25(OH)D (12.4 vs. 25.9 ng/mL, p &lt; 0.001) and a reduced level of 24,25(OH)₂D₃ (0.6 vs. 1.5 ng/mL, p=0.001) were noted. Assessment of bone tissue revealed a significantly lower Trabecular Bone Score (TBS) in the LC group (1.370 vs. 1.498, p=0.001), while no differences in absolute BMD values were observed.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: The study results confirm the presence of specific features of mineral metabolism in patients with LC: alterations in vitamin D metabolism, hypocalcemia, reduced PTH concentration, and impaired bone microarchitecture (decreased TBS) with preserved BMD. This highlights the need for comprehensive examination of patients with LC and further research on this issue.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хронические заболевания печени</kwd><kwd>цирроз печени</kwd><kwd>печеночная остеодистрофия</kwd><kwd>минеральные нарушения</kwd><kwd>остеопороз</kwd><kwd>витамин D</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic liver diseases</kwd><kwd>liver cirrhosis</kwd><kwd>hepatic osteodystrophy</kwd><kwd>mineral disorders</kwd><kwd>osteoporosis</kwd><kwd>vitamin D</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа проведена в рамках гранта РНФ №24-25-00348 «Нарушения метаболизма витамина D и особенности костного ремоделирования у пациентов с циррозом печени различной этиологии».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sepanlou SG, Safiri S, Bisignano C, et al.
